Bontrager XR2 26" TLR

Looking for a lightweight tubeless ready rear tire for hardpack. The Bontrager XR2 TLR looks good and reviews are just as positive. Plus they have a 30 day return policy if the $45 Expert or the $55 Team (weighs about 100g less) didn't make you happy. Thinking the 1.9 or 2.1 for my 26" rear wheel.
